Introduction Functionally Graded Materials (FGMs) are advanced composite materials to protect large temperature gradients in a structure.
Usually, two materials are composed linearly by the rule of mixture through the thickness direction.
The deviation is dependent only on the Young's moduli of two materials [4].

The development of measuring techniques allows of the in situ observation of the solidification processes and the elimination of flows and so the experimental control of the simple diffusion models have become possible by means of the space material science.
Several journals are available for publication of the research results.
In the conference the results of researches obtained by ESA and NASA in the field of material science as well as the two solidification projects of ESA (MICAST, CETSOL) were presented on plenary sessions.
